摘要
应用系统动力学专用的仿真软件VENSIM对不同峰谷分时电价定价策略和不同响应类型用户进行仿真和比较研究。研究表明:①最优的峰谷分时电价结构是峰谷基价随发电电价和供电利润动态调整,峰谷电价比在峰谷电价实行初期固定不变,当负荷趋于平稳后随系统负荷特性动态调整;②不同响应类型的用户具有不同的最满意峰谷电价结构,因此,针对不同用户,应设置不同的峰谷电价结构参数;③在供需利益均衡机制作用下,平均电价呈衰减振荡趋势,振荡幅度与峰谷价差和滞后时间成正比,因此峰谷价差要结合削峰填谷目标、平均电价波动幅度和用户承受能力综合考虑。同时,尽可能缩短电价调整时间,平稳价格波动,提高峰谷电价政策的社会效益。
Simulation and comparison studies of different peak and valley time price policies and different response types of users are carried out by simulation software VENSIM special for system dynamics. The simulation results show that： （1）The optimal price structure is that the base price is regulated with generation price and power supply benefits, and the ratio between peak and valley prices is fixed in the initial implementation stages and then adjusted with load characteristic when load become stable. （2）Different response type of users have different satisfied price structure, so the price structure parameters should be set differently. （3）The average price presents attenuated damping trend under the operation of the supply and demand benefit equilibrium mechanism , and the damping amplitude is proportional to the lingering time and the peak and valley price difference which should comprehensively consider the target of peak load shifting, average price fluctuation amplitude and user＇ s enduring capability. Simultaneously, it should also shorten the price regulation time as short as possible, and smooth the price fluctuation to increase the social benefits of peak and valley price policy.
